    Hey everyone,

    I've been working on getting my OBS settings right for my YouTube channel, and I'd really appreciate some input from the community on my current settings.
    I've been having problems with recorded footage being extremely choppy,
    as if OBS is recording in slow motion. Dropped frames?

    Anyway, I'm now using OBS settings I got from a YouTube video, and the frame rate seems better.
    I've uploaded a test video to YouTube (unlisted link below), and I'm curious what you all think.

    My System Specs:

    • Windows 11 Pro
    • AMD Ryzen 9 9950X3D 16 Core
    • RTX 5090
    • 96GB RAM @6000MHz
    Windows Settings:

    • Power Setting: Balanced
    • Optimizations for windowed games: On
    • Hardware Accelerated GPU Scheduling: On
    • Game Mode: Off
    Nvidia Control Panel:

    • G-Sync: Off
    • Anisotropic filtering: 16X
    • Monitor Technology: Fixed Refresh
    • Power Management: Prefer Maximum Performance
    • Preferred Refresh Rate: Application Controlled
    • Shader Cache Size: 100GB
    • Texture Filtering: High Performance
    • V Sync: Use the 3D application settings
    OBS Studio Settings:

    • Output Mode: Advanced
    • Recording Format: Matroska Video (.mkv)
    • Video Encoder: NVIDIA NVENC HEVC
    • Audio Encoder: FFmpeg AAC
    • Rate Control: Constant QP (CQP 25)
    • Keyframe Interval: 2 seconds
    • Preset: P5 (Slow - Good Quality)
    • Tuning: High Quality
    • Multipass Mode: Two Passes (Quarter Resolution)
    • Profile: Main
    • Adaptive Quantization: Enabled
    • B-Frames: 2
    (After recording, I remux to MP4, then edit and render with Davinci Resolve, with render settings as close as possible to the recording settings.)

    In-Game Graphics:

    • Windowed Fullscreen
    • Foliage Quality: Ultra
    • Shadow Quality: High
    • Effects Quality: High
    • Sky Quality: Very High
    • Fog Quality: Ultra
    • Post Process Quality: Ultra
    • View Distance Quality: Ultra
    • Texture Quality: Ultra
    • Max FPS: Unlimited
    • AntiAliasing: TAA
    • VSync: On
    • Screen Percentage: 120%
    (I'm not using Nvidia Smooth Motion or Lossless Scaling)

    Recording at 3840x2160 60fps.

    With these settings I'm getting about 70fps on the Crewe to Birmingham route (where the clip is recorded from). It looks okay to me, with these OBS settings, a 69 minute recording comes out to about 18.5GB in size.

    I could probably increase the quality settings a bit.
    Anyway, apart from your opinions on any of the settings I'm using, I'm especially interested in your thoughts about the frame rate, does it look smooth to you guys?



    Edit: I have changed the recording format to hybrid MP4, and set CQP to 16.
    This gave me much better quality for 1.3GB per minute of video.

    I can't see the videos as I'm on mobile, so based on your post:
    Do you have multiple monitors? May be an idea if you do to have the game open on one and OBS on another, then you can monitor the frame rate it records at in real time.

    Try capping the FPS in-game to 60 if you're recording at 60, mismatched frame rates can cause issues.

    Are you using game capture, window capture or desktop capture in OBS?

    You could get away with dropping the resolution to 1440p or even 1080p - as I understand it, most people watch on small screens (ie, phones), and/or don't watch fullscreen, so super high resolutions aren't really necessary.

    Only have one monitor, I'll keep the settings I'm using for now. Just did the full service as on the clips I shared, and everything seems fine. But I'll try your suggestion on capping the frame rate to 60 in game. If it still holds up on the WCMLS with OTS's timetable mod, I'll stick with it.
